Mitigation Measure N-1: Conduct all construction activities involving motorized equipment between the hours of 7 a.m. and 7 p.m. Monday through Saturday, or for a shorter period if so stipulated in the applicable noise ordinance. Further restrict construction to outside school hours where schools are located near the ROW and would be impacted by construction noise. Incorporate these restrictions in all construction plans and scheduling prior to construction. Compliance during planning and construction is to be monitored by the city/county agency that enforces the noise ordinance, by the Public Works Department, or by a CPUC/ANF-approved construction monitor. This measure is to be overridden by transportation measure T-3 where it conflicts with the provisions therein.
Impact: Impact on sensitive receptors (Class II or III).
Performance Criteria, Violation Level, and Timing:
PC1 All construction activities occur between 7 a.m. and 7 p.m. Monday through Saturday (or for a shorter period if stipulated by applicable noise ordinance). No construction activities may occur on Sunday. (Level 2) - During construction.
PC2 Construction activities occur outside school hours when schools are located within 300 feet of centerline of the right-of-way of the construction area. (Level 2) - During construction.
PC3 PPSI provides copies of noise ordinances and documents where each one is applicable. (Level 2) - Prior to construction.
PC4 PPSI complies with all applicable city/county noise ordinances. (Level 3) - During construction.
Effectiveness Criteria: Verification of construction activities during specified hours will result in impact reduction.
Effectiveness Timing: During construction.
Mitigation Measure N-2: The Applicant/contractor shall provide 72-hour advance notice to all sensitive receptors identified as potentially subject to either some or severe noise impact during construction (see Tables; implement with L-1 through L-3). Notification shall be by mail with telephone follow up. The announcement shall state where and when construction will be scheduled in the subject's area. It shall further provide tips on reducing noise intrusion, for example, by closing windows facing the planned construction. The noticing shall also advise the recipient on how to inform the Applicant/contractor if specific outdoor events are scheduled so that construction can be rescheduled, if necessary, to avoid a conflict. A reasonable deadline for notification shall be stated. Compliance is to be monitored by a CPUC/ANF-approved construction monitor.
Impact: Impact on sensitive receptors (Class II or III).
Performance Criteria, Violation Level, and Timing:
PC1 PPSI provides a copy of the advance notice and a list of sensitive receptors (which shall include those listed in Tables C.9-8 and C.9-9 of the FEIS/SEIR and supplemented by additional receptors, if any, identified during preconstruction survyes) that will receive a minimum of 72-hour advance notice of construction noise. (Level 1) - Three weeks prior to initiating construction within the area of concern.
PC2 PPSI provides documentation of mailing a 72-hour advance notice to all sensitive receptors and documents attempts at telephone follow up. (Level 2) - Mailed at least 5 days prior to construction in the area of concern.
PC3 PPSI assigns monitor to ensure compliance with this mitigation measures. (Level 1) - Monitor assigned prior to start of construction and ensures compliance during construction.
PC4 Schools on the sensitive receptor list will include those that fall within 300 feet of the centerline of the construction ROW (unless PPSI can demonstrate through noise modeling, that no significant impact would result at any school within that range. - (Level 1) - Three weeks prior to initiating construction within the area of concern.
Effectiveness Criteria: Verification of the appropriate sensitive receptor locations, and review of the notice-letter. Notifying the appropriate receptors will result in an impact reduction.
Effectiveness Timing: Prior to and during construction
Mitigation Measure N-3: Establish an 800 telephone number for receiving complaints during construction and develop procedures for responding to them. The number shall be included in the mailed notification (Mitigation Measure N-2) and implemented with Mitigation Measures L-1 through L-3.
Impact: Impact on sensitive receptors (Class II or III).
Performance Criteria, Violation Level, and Timing:
PC1 PPSI establishes an 800-telephone number for public contact (Level 1) - Prior to construction.
PC2 PPSI develops a procedures for documenting each telephone call (the time, the date, and a summary of the complaint) and for responding to the complaints. (Level 1) - Prior to construction.
PC3 PPSI implements complaint procedures. (Level 2) - Prior to construction.
Effectiveness Criteria: Verification of the 800-telephone number and active log book.
Effectiveness Timing: Before and during construction.
Mitigation Measure N-4: Maintain proper mufflers on all internal combustion and vehicle engines used in construction to reduce noise to the maximum feasible extent. A CPUC/ANF-approved construction monitor shall see to compliance through periodic checks of the equipment and its operation, or by making use of noise measurements periodically over the complete construction schedule.
Impact: Impact on sensitive receptors (Class II or III).
Performance Criteria, Violation Level, and Timing:
PC1 PPSI provides a certification (signed and dated) from a third-party independent Certified Mechanic that the muffler installed on each applicable machine/vehicle is proper and maintained. The identification number for each machine/vehicle must be listed on the certification form, as well as on the outside (in plain view) of each machine/vehicle. (Level 2) - Prior to construction.
PC2 PPSI monitors conduct and document periodic checks of the equipment and construction activities periodically over the complete construction schedule to ensure that noise levels are reduced by properly functioning mufflers. (Level 2) - During construction.
Effectiveness Criteria: Verification of the operational functionality of the mufflers will result in an impact reduction.
Effectiveness Timing: Before and during construction.
